Domain OSINT, TLS Certificate & Security Headers Recon is a paid API for AI agents from shopify-spy.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).
Performs live DNS resolution (IPv4/IPv6), TLS certificate inspection (issuer/expiry), and HTTP security header grading for a given domain.

How this service works
Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade. (Live x402 v2, IETF MPP & MCP endpoint at https://shopify-spy.agentdiet.dev/v1/subdomain-scan)
Output
Returns live DNS resolution results (IPv4 and IPv6 addresses), TLS certificate details (issuer organization, expiry date), and an HTTP security header grade/analysis — giving a full infrastructure and security posture snapshot for the target domain.
Example use cases
Pre-deployment security check
“Before we go live, can you audit openai.com's TLS certificate — tell me who issued it, when it expires, and whether the HTTP security headers are configured properly?”
Competitor infrastructure recon
“I want to do some OSINT on stripe.com — can you pull its live DNS records, check the TLS cert details, and grade its HTTP security headers?”
Certificate expiry monitoring
“Can you check if the TLS certificate on mycompany.com is about to expire and who issued it, so I can plan a renewal?”
Technical details
Endpoint
GEThttps://shopify-spy.agentdiet.dev/v1/subdomain-scan?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need live, real-time DNS, TLS, and HTTP security intelligence about a specific domain in a single call — ideal for security audits, competitor recon, certificate monitoring, or pre-deployment checks. Prefer this over passive WHOIS-only tools when you need actual TLS cert issuer/expiry and active security header grading.
Side effects
- Domain does not resolve — returns empty DNS results or error if the domain is unreachable
- TLS certificate absent — no cert data returned for HTTP-only or misconfigured domains
- Invalid domain input — error if the domain string is malformed or empty
- Timeout — live probing may fail if the target is slow or unreachable
- Rate limiting — repeated rapid calls may be throttled or return 402 payment required
